本考案は不凍給水栓の改良に関わり、特に同一
出願人による実公昭58−40136号公報の改良に関
するものである。[Detailed Description of the Invention] The present invention relates to an improvement of an antifreeze faucet, and particularly relates to an improvement of Japanese Utility Model Publication No. 40136/1983 by the same applicant.

わせるようにしたものであり、上記リング状パツ
キンの事故を完全に防止したものである。 The cited example above is caused by a defect in the conventional anti-freeze faucet where the ring-shaped gasket adheres to and separates from the cylinder to shut off water, that is, the ring-shaped gasket easily protrudes from the groove due to the force of flowing water. In order to eliminate the defect of being easily cut, the valve body, which has two flat packings and two sleeves, is moved up and down between the two valve seats of the valve body and the cylinder, which are positioned to sandwich the valve body. Then, before one sleeve separates from the cylinder, the other sleeve comes into close contact with the other cylinder, and eventually the flat packing closes the valve seat to allow water to flow and drain. This completely prevents the above-mentioned ring-shaped packing accident.

かねないこと、等の欠陥があつた。 However, with the above-mentioned valve, the valve body cannot be pulled out from above the pipe, so when repairing the valve body, it is necessary to dig up the soil each time.
Therefore, it is unsuitable for deep burial in extremely cold regions, and a backflow prevention valve is usually installed at the drain outlet to prevent underground sewage from entering the valve box.
Even in the event that the backflow prevention valve malfunctions, it is necessary to dig out of the ground, and since the valve body also rotates when the handle is rotated, the seal can easily loosen, causing water leakage. There were flaws such as things that could happen.

29は漏水防止用Oリングである。 In Fig. 1, 1 is the valve box of the antifreeze faucet of the present invention, which has an inlet 2 and an outlet 3 on the sides, a cylinder 4 vertically in the middle thereof, and a cylinder 4 at the upper end of the cylinder 4. An upward facing valve seat 5 is formed. A valve cover 6 is connected to the upper end of the valve box 1, and a valve seat body 9 having a cylinder 7 inside and forming a downward valve seat 8 at the lower end is connected to the lower end of the valve cover 6. The valve cover 6 has a female thread 10 for operation inside, and a first drain hole 11 above it.
Drill horizontally. Inside the valve cover 6, a spindle 13 having a male operating thread 12 that is screwed into the female operating thread 10 is housed, and the spindle 13 has a communication hole 14 formed therein that communicates with the first drain port 11. A ball-shaped check valve 15 is seated and accommodated in the communication hole 14 facing downward. The spindle 13 has a U-shaped groove 16 cut out on its side as shown in FIG. 2 at its lower end, and a valve body 18 on its upper end which has a flange 17 that fits into the U-shaped groove. The spindle 13 and the valve body 18 are rotatably connected by inserting the valve body 18 from the opposite direction. The valve body 18 has a flat packing 1 at the lower end.
9. Attach the sleeve 20 below it with screws 21 so that it will not come off, and also attach the flat packing 19' and the sleeve 20' above it. In other words, the flat packing 19 and the sleeve 20 are arranged so that they can be closely removed from the valve seat 5 and the cylinder 4, and the flat packing 19' and the sleeve 20' are arranged so that they can be closely removed and removed from the valve seat 8 and the cylinder 7. sleeve 2
0 and 20' are made of relatively soft plastic or hard rubber so that they do not deform due to the flow of water and allow the cylinders 4 and 7 to slide relatively smoothly. Reference numeral 22 denotes a mantle pipe connected to the upper end of the valve box 1, and a second drain port 23 is bored on the side. 24 is an inner cannula connected to the upper end of the valve lid 6, and the operating section main body 25 is connected to the upper end. A rod 26 is connected to the upper end of the spindle, and an operating rod 27 is connected to the upper end so as to protrude upward from the operating section main body 25. In addition, 28 is a handle,
29 is an O-ring for preventing water leakage.
次に作動態様を説明する。 Next, the operating mode will be explained.
第1図は通水状態を示しており、流入口2から
の水はシリンダ4、流出口3を通つて図示しない
が下流側配管へと流れ、末端の蛇口に至つてい

着しており、上方への漏水を防止している。 FIG. 1 shows a state in which water is flowing, and water from the inlet 2 flows through the cylinder 4 and the outlet 3 to the downstream piping (not shown), and reaches the faucet at the end. In this state, the flat packing 19' is in close contact with the valve seat 8, preventing water from leaking upward.

ブ20がシリンダ4から離脱する前にスリーブ2

らの水が排水口側へ流出することはない。 When you want to operate the antifreeze faucet to drain water from this state, turn the handle 28 in either direction and the spindle 13 will be screwed onto the valve cover 6.
falls while rotating, and at the same time, the valve body 18, which is rotatably connected to the spindle 13, begins to fall without rotating due to the frictional force between the cylinder 7 and the sleeve 20'. At this time, the flat packing 19' separates from the valve seat, but water does not leak upward due to the sleeve 20', and before the sleeve 20' separates from the cylinder 7, the lower sleeve 20 comes into close contact with the cylinder 4. Cut off water from inlet 2. Thereafter, the sleeve 20' separates from the cylinder 7, and finally the flat packing 19 comes into close contact with the valve seat 5, and the valve body 18 stops descending. Therefore, water in the downstream piping passes through the gap between the cylinder 7 and the valve body 18 from the outlet 3, flows through the opening of the U-shaped groove 16 of the spindle 13, and flows into the communication hole 14, causing the check valve 15 to flow into the communication hole 14. It is lifted and discharged into the ground through the first drain port 11 drilled in the valve lid 6 and the second drain port 23 drilled in the mantle pipe 22. When the drainage is finished, the check valve 15 falls under its own weight and blocks the communication hole, so that together with the O-ring 29, underground sewage does not enter the outlet 3 side. To make water flow again, simply rotate the handle 28 in the opposite direction, and this time, before the sleeve 20 separates from the cylinder 4, the sleeve 2
0' is in close contact with the cylinder 7, so water from the inlet 2 does not flow out to the drain port side.
なお、スリーブ20がシリンダ4に進入してい
くことにより、流入口2側の水の圧縮による圧力
上昇が起こるため、それを避ける目的で、スリー
ブ表面に浅い螺旋溝をもうけるなどして、微量の
水を流出口3側に逃がしてやることもできる。 In addition, as the sleeve 20 enters the cylinder 4, a pressure increase occurs due to the compression of water on the inlet port 2 side, so in order to avoid this, a shallow spiral groove is formed on the sleeve surface, etc. It is also possible to let water escape to the outlet 3 side.

できるものである。 In any case, since the spindle 13 and the valve body 18 are rotatably connected, when the valve body 18 moves up and down, no unreasonable rotational force is applied to the flat packings 20, 20'. 20, 20' will not come loose or the flat packing 20, 20' will not be torn off, and this combined with the fact that the conventional ring-shaped packing is not used prevents water leakage accidents. This is unlikely to occur, and by providing a U-shaped groove 16 cut in the side surface of the spindle 13, the connection between the spindle 13 and the valve body 18 can be made very easily. Simply rotate the main body 25 and remove the valve cover 6 from the valve box 1.
The check valve 15 or the seal 1 of the valve body 18 can be easily installed on the ground without digging underground.
9, 19' and the sleeves 20, 20' can be repaired and inspected, so it can be easily applied even in extremely cold regions where they are buried deep.
